In this paper, we design a dual reflector antenna that can be used for satellite communication and evaluate its performance. First, the design center frequency is determined for the design of the corrugated horn antenna, and the change of the characteristic according to the variation of the wall thickness and the slot width of the corrugate is investigated. In order to suppress the reflected wave generated by the corrugate, suitable input tapere section must be designed and a mode conversion section is desiged in order that the cross polarization does not occur. In order to suppress the occurrence of the mode, the height of the corrugate is calculated in the transition section and the output flare section, the center point of the phase is calculated, and the horn characteristics are calculated at the highest and lowest frequencies. In order to analyze the antenna radiation characteristics of the offset reflective plate, we analyze the radiation characteristics of the sub reflector using the diffraction geometry theory, analyze the radiation characteristics of the main reflector using the physical optics method, Combine to interpret the radiation characteristics of the reflector antenna. |
